Why would I chose one over the other?

Comments

The main one is that mono is more efficient so you can get more W/ft^2. If you are space constrained then you want mono. But the $/W is generally higher. 
Poly are less costly per watt so if you have more room they often are a less costly option overall. There are other differences but often it comes down to these.
What about heat, is there a difference.  For example we are Bay Area installers, if we are installing in the Delta or Sacramento Valley, is there any practical difference with higher temperatures?

thank you for the good information.
